Generally speaking, stock cancellation is a neutral news, and there is no difference between good and bad. For example, the "cancellation of some stock options" is due to the resignation of some managers who could have obtained the option, and the company only subtracts the option from the original number of options, which has little impact on the company. After the repurchase is completed, the listed company will cancel the repurchased shares, and the cancelled shares will no longer participate in the stock issuance, nor participate in the calculation and distribution of income. But in this case, the share price may rise, and the reason for the rise is not because of the cancellation of shares, but the repurchase policy. Stock repurchase is a signal that listed companies send to the market that their share prices are undervalued. Therefore, after the repurchase, the number of shares in circulation will decrease, and the profit per share will increase if the total profit remains unchanged. So it is good in the long run, which not only stabilizes the stock price, but also improves the competitiveness of the company.

1. Stock option: Stock option refers to the right of the buyer to buy or sell a certain number of relevant stocks at the agreed price on or after the expiration date stipulated in the contract after paying the option fee. It is one of many ways to motivate employees and belongs to the category of long-term motivation. Stock option is the right given by listed companies to senior managers and technical backbones of enterprises to buy their common shares at a pre-agreed price within a certain period of time. Stock option is a brand-new incentive mechanism different from employee stock, which can effectively combine senior talents with their own interests. The exercise of stock options will increase the owner's equity of the company. The holder buys the issued shares from the company, that is, directly from the company rather than from the secondary market.

2. Option futures: In futures trading, buyers and sellers stipulate equal rights and obligations in the contract. In option trading, the buyer has the right to buy or sell futures contracts at the price stipulated in the contract, and the seller has the obligation to perform passively. Once the buyer puts forward the execution, the seller must solve his option status by performing the contract.

3. Profit and loss structure: In futures trading, with the change of futures price, both buyers and sellers are faced with unlimited profits and losses. In option trading, the potential profit of the buyer is uncertain, but the loss is limited and the maximum risk is certain; On the contrary, the seller's income is limited, but the potential loss is uncertain.
